Abstract

The invention relates to a TOF camera system comprising several cameras, at least one of the cameras being a TOF camera, wherein the cameras are assembled on a common substrate and are imaging the same scene simultaneously and wherein at least two cameras are driven by different driving parameters.

Claims (10)

1. A Time-Of-Flight (TOF) camera system comprising:

a plurality of sensors, the plurality of sensors including a TOF sensor and a color image sensor, wherein the TOF sensor and the color image sensor are assembled on a common substrate and are configured to image a same scene simultaneously; and

circuitry configured to drive a first sensor of the plurality of sensors with first driving parameters and to drive a second sensor of the plurality of sensors with second driving parameters different than the first driving parameters.

2. A TOF camera system according to claim 1 , wherein the first driving parameters and the second driving parameters comprise at least two different frequencies for implementing a dealiasing algorithm.

3. A TOF camera system according to claim 1 , further comprising an array of lenses, each lens of the array being associated with a respective sensor of the plurality of sensors.

4. A TOF camera system according to claim 2 , wherein the at least two different frequencies comprise modulation frequencies configured to control the timing of the imaging of the scene.

5. A TOF camera system according to claim 2 , wherein the dealiasing algorithm includes instructions to distinguish between two potential distance measurements generated by the TOF sensor.

6. A TOF camera system according to claim 2 , wherein both of the first sensor and the second sensor are TOF sensors.

7. A TOF camera system according to claim 6 , wherein the circuitry is further configured to generate a dealiased depth map by combining the depth measurements from the first sensor and the second sensor.

8. A TOF camera system according to claim 2 , wherein the circuitry is further configured to implement at least two dealiasing algorithms.
